3.1 Restrictions on Short Selling
- Except as otherwise provided, a Participant or Access Person shall not make a short sale of a security on a marketplace unless the price is at or above the last sale price.
- A short sale of a security may be made on a marketplace at a price below the last sale price if the sale is:
- a Program Trade in accordance with Marketplace Rules;
- made in furtherance of the Marketplace Trading Obligations of that marketplace;
- for an arbitrage account and the seller knows or has reasonable grounds to believe that an offer enabling the seller to cover the sale is then available and the seller intends to accept such offer immediately;
- for the account of a derivatives market maker and is made:
- in accordance with the market making obligations of the seller in connection with the security or a related security, and
- to hedge a pre-existing position in the security or a related security;
- the first sale of the security on any marketplace made on an ex-dividend, ex-rights or ex-distribution basis and the price of the sale is not less than the last sale price reduced by the cash value of the dividend, right or other distribution;
- the result of:
- a Call Market Order,
- a Market-on-Close Order,
- a Volume-Weighted Average Price Order,
- a Basis Order, or
- a Closing Price Order;
- a trade in an Exempt Exchange-traded Fund; or
- made to satisfy an obligation to fill an order imposed on a Participant or Access Person by any provision of UMIR or a Policy.
POLICY 3.1 – RESTRICTIONS ON SHORT SELLING
Part 1 – Entry of Short Sales Prior to the Opening
Prior to the opening of a marketplace on a trading day, a short sale may not be entered on that marketplace as a market order and must be entered as a limit order and have a limit price at or above the last sale price of that security as indicated in a consolidated market display (or at or above the previous day’s close reduced by the amount of a dividend or distribution if the security will commence ex-trading on the opening).
Part 2 – Short Sale Price When Trading Ex-Distribution
When reducing the price of a previous trade by the amount of a distribution, it is possible that the price of the security will be between the trading increments. (For example, a stock at $10 with a dividend of $0.125 would have an ex-dividend price of $9.875. A short sale order could only be entered at $9.87 or $9.88.) Where such a situation occurs, the price of the short sale order should be set no lower than the next highest price. (In the example, the minimum price for the short sale would be $9.88, being the next highest price at which an order may be entered to the ex-dividend price of $9.875).
In the case of a distribution of securities (other than a stock split) the value of the distribution is not determined until the security that is distributed has traded. (For example, if shareholders of ABC Co. receive shares of XYZ Co. in a distribution, an initial short sale of ABC on an ex-distribution basis may not be made at a price below the previous trade until XYZ Co. has traded and a value determined).
Once a security has traded on an ex-distribution basis, the regular short sale rule applies and the relevant price is the previous trade.
